Goodyear this week announced it's developing a tire that automatically stays inflated to the proper tire pressure, thanks to an embedded miniature pump. The technology will help motorists save on gas and also will mean they won't have to change their tires as frequently, the company says.

The World Trade Organization has supported the Obama administration's decision in September 2009 to enact tariffs on Chinese tires imported to the U.S. The WTO said the president's claim that such imports disrupted the domestic tire market was warranted.

Tires are getting more expensive across the world.
Goodyear Tire & Rubber Co. (GTR) and Cooper Tire & Rubber Co., (CTB) the two largest U.S. tiremakers, plan to raise prices by as much as 6.5% starting October, according to Bloomberg News. In Europe, Bridgestone (BRDCY) is upping its prices by about 6%.
